Abstract (en)
Disclosed herein is a low shrinkable unsaturated polyester resin composition consisting of(A) 20-70% by weight of an unsaturated polyester;(B) 28-60% by weight of a monomer polymerizable with the above unsaturated polyester,(C) 2-20% by weight of a block copolymer mixture defined in the following, and in which a mixture of the monomer (B) and the block copolymer mixture (C) is in a non-aqueous dispersion state; and a mixture of the above polyester (A), the monomer (B) and the block copolymer mixture (C) is in a non-aqueous dispersion state, said block copolymer mixture is a copolymer obtained by polymerizing either one of monomers defined below in (a) and (b) (hereinafter referred to as monomer (a) and monomer (b) respectively) or a mixture thereof by using as a polymerization initiator a polymeric peroxide represented by the general formula:in which R, represents a divalent branched hydrocarbon group having 10-30 carbons, and R<sub>2</sub> and R<sub>3</sub> represent a hydrogen atom, a hydroxyl group or an alkali metal; and the average polymerization degree n is 2-40, and it is used to obtain a polymer (a first polymerization reaction) having peroxy bonds in its molecule, and block-polymerizing this polymer with the monomer or a mixture of the monomers which has not been used in the first polymerization reaction.(a) A monomer or a monomer mixture consisting of 70-100% by weight of styrene monomer and 30-0% by weight of a monomer polymerizable therewith(b) A monomer or a mixture of monomers consisting of 70-100% by weight of a C<sub>1-4</sub> alkyl ester of acrylic acid or methacrylic acid and 30-0% by weight of a monomer polymerizable therewith.
